I've had a productive cough for nearly 6 months, as well as chest pain on left side of breast bone. 27 year-old male, who smoked for a year. cancer?

Possible, but doubt: Lung cancer can occur in 27 yrs old who smokes, but chance is very low. Even if it is cancer, not likely from smoking at this point. If having lung cancer is causing severechest pain, you likely have other symptoms as well..Wt loss, fatigue/malaise, coughing, night sweat etc...So, your symptom of pain likely musculoskeletal strain/sprain. Please see doc for eval..U should stop smoking! good luck.

Check with your doc: Highly unlikely, and probably something else is going on. Better check with your doc to be safe.

Get it checked: You smoke and have been coughing for 6 months, it is about time you consult a physician to find the cause.It is unlikely that you have cancer.More common causes og prolonged cough is chronic bronchitis, copd, bronchial asthma, the cancer possibility at the bottom of the totum pole. Your chest pain may be from coughing, pneumonia and pleurisy etc.You will need a chest xray and thorogh physical exam&pft.
